ELECTRICAL CHARACTERISTICS The
l
denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. Test conditions are V+ = 2.25V to 5.5V, TRIG = 0V, DIVCODE = 0 to 15
(NDIV = 1 to 221), RSET = 50k to 800k, RLOAD = 5k, CLOAD = 5pF unless otherwise noted.
